As quality of life (QOL) could be influenced by oral status in the elderly, we examined whether chewing ability or number of teeth affected QOL in 80-year olds. A cross-sectional survey included dental examination, chewing self-assessment, and a QOL questionnaire. A total of 823 people who were 80 years old participated in this study. QOL was assessed in terms of satisfaction with physical condition, meals, daily living and social interactions, and with face-scale scores. After adjustment for gender, spouse and activities of daily living, dissatisfaction with social interactions was 3.9 times more prevalent in individuals able to chew four foods or fewer than in those chewing 15. Dissatisfaction with physical condition, meals and daily living, and poor face-scale scores, were 2.7, 2.4, 3.4, and 2.4 times more prevalent, respectively, in subjects chewing four foods or fewer. The number of teeth showed little effect. In conclusion, self-assessed chewing ability but not number of teeth was associated with QOL in 80-year-old subjects.
由于生活质量（QOL）可能会受到老年人口腔状况的影响，我们研究了咀嚼能力或牙齿数量是否会影响80岁老人的生活质量。一项横断面调查包括牙科检查、咀嚼自我评估和一份生活质量问卷。共有823名80岁的人参与了这项研究。生活质量是根据对身体状况、饮食、日常生活和社交互动的满意度以及面部量表评分来评估的。在对性别、配偶和日常生活活动进行调整后，能够咀嚼四种或更少食物的个体对社交互动的不满发生率是能够咀嚼15种食物的个体的3.9倍。在咀嚼四种或更少食物的受试者中，对身体状况、饮食和日常生活的不满以及较差的面部量表评分的发生率分别高出2.7倍、2.4倍、3.4倍和2.4倍。牙齿数量的影响很小。总之，在80岁的受试者中，自我评估的咀嚼能力而非牙齿数量与生活质量相关。
